Abstract: The present disclosure relates to a display system that enables video representation of higher quality. A display includes a plurality of light sources and a light absorption layer that forms a display surface and absorbs external light applied to the display surface. An opening through which light from the light sources is emitted toward a side of the display surface is formed in the light absorption layer. The technology according to the present disclosure may be applied to, for example, a tiling display.

Abstract: In an apparatus for generating and managing production processing structure in a production management system of a factory, the structure of factory made up of the names or other identifiers of process points obtained by subdividing the factory production line is hierarchically registered in the storage device of the management computer (server; S200), the terminal computers and devices used in production are registered as terminal devices (S202), and tasks (from among tasks generated in advance and stored in the disk of the management computer) for achieving the operation or processing to be implemented at the process points are selected for each process point and registered in the order of execution (S204), while linking the terminal devices with definition information that correlates them, once the terminal computers are activated, the registered tasks are executed by the management computer (server) based on the definition information thus registered, so that the production record information is accumulat

Abstract: A system for inverter control of a servo motor where in the inverter is connected to a velocity control section and a position detection section is connected to the servo motor. Primary and back-up power for operating the velocity control section and the position detection section is provided by power sources that are located in the velocity control section and are connected to the position detection section by cables. The cables used to provide signal transmission between the position detecting section and the velocity control section are switched by relays to transmit the power of a power failure back-up power supply at the time of a power failure. Also, a transmission signal transmitted from one of the position detecting section and the velocity control section to the other via a first cable connection is returned via a second cable connection and a connection fault may be judged depending on whether or not the return signal matches the transmission signal.

Abstract: A servo motor system for a transportation line with the travel distance of the article predetermined and with a relatively low positioning accuracy. Basically, the system is constructed as an incremental servo motor system in which an incremental movement of the motor is detected, and the incremental movement signal is fed back to a motor driver, which also receives pulse signals from a controller corresponding to a traveling distance to a destination. Only one time after starting the operation of the servo motor system with the article not at the destination point, a stop signal is fed from an external signal generator located at the destination point to the motor driver, which stops the motor there. At this time, a coordinate system of the movable space of the article is established in the controller and the servo motor system is operated as an incremental system from the second time on, without utilizing an external signal generator.
